The FBI arrests a serial killer John Mostow, responsible for the killing of at least 7 men. Mostow claims he was possessed by an evil spirit, a fairly common claim among serial killers as Scully points out. With Mostow in custody however, other very similar attacks occur leading Mulder to think Mostow may be telling the truth. The agent in charge of the case, the renowned Bill Patterson, doesn't think much of Mulder or the kind of cases he deals in. As the killings continue however, the evidence not only points to Mulder's theory being correct but points to the killer. Written by garykmcd

When Mostow's cell shutter is opened, the light from the corridor is extremely bright, yet when Mulder and Scully enter the cell the light is less harsh. At the bottom right of the door as it is opened a crew member's leg can briefly be seen, presumably taking the first, brighter light out of the frame. See more »


Agent Bill Patterson: My advice to you, Scully: Let Mulder do what he has to do. Don't get in his way. And don't try to hold him back because you won't be able to.

Awesome underrated classic
1 December 2006 | by Dorian-KellawaySee all my reviews

Grotesque is quite possibly the most underrated x file ever. It tells the story of Agent Bill Pattersons catching of a serial killer who claimed to be possessed by an evil spirit. The killer spent his time painting and sculpting gargoyles. As the murders and facial mutilation of young men continues Mulder and Scully begin the investigation Mulder often clashing with Patterson over the approach to violent crimes. Mulder dives deeper and deeper into the case until it borders on insanity. The whole episode has an edge to it, it gives the viewer little knowledge as to what exactly is happening and whose doing it. The class in this episode is in its creation, directed by Kim Manners he creates arguably one of the darkest X files ever. Mark Snow provides a fantastic musical score and it stands apart from nearly any other x file you will see. Im sure certain people were turned off by it abandoning some conventions of Mulder and Scullys investigative approach and teamwork they separate bitterly in this episode. In general it is far more like a stylised film than a television episode. If you want a dark edgy atmospheric powerful thriller that really shys away from typical x file approach, combined with one of Duchovnys best performances as Fox Mulder then turn out the lights and watch Grotesque.
